No, I have not done this DIY. However, I have built radios and other electronic devices in the past as a hobby.

I wouldn't recommend a soldering gun but instead a solder iron. It's lighter and more maneuverable than a bulky gun.

I would not know the difference...I probably melt the damn board with either one. probably cause self inflicted pain as well with them. This is going over board, but could I request a video DIY on this?
